Launching her career in cinema, June Lockhart, who passed on aged 100, achieved her biggest success after switching predominantly to television. Having been given limited opportunities to excel in movies from her debut as a child in 1938 until 1947, she excelled on television in many beloved series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
In her role as a housewife, Lockhart somehow managed to avoid being completely overshadowed by the intelligent canine. She described the program as “a fairy tale about families on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six sexless years of playing a country wife and mother, I was rarely permitted to kiss my co-star on the cheek.”
Starring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the show continued, the storyline became increasingly less about this interstellar family and increasingly about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in dozens of films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.
Her first stage appearance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her father was given a contract by a film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her professional life in films, mostly in minor roles in prestigious pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the latter, she is charming as a New Yorker at a family party, whose schedule is arranged spitefully to stop Lockhart interacting with her brother.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who helps the dog to return to the owners. In the subsequent film, Lockhart played the now adult character.
The loving way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV would be the answer. Before embarking in a different direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Career and Legacy
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie version starring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandkids.
